If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration. In a diesel engine, a bad EGR valve is one of the causes of a black smoke. The Check Engine light might ...
The engine computer helps in opening or closing the EGR valve to control the flow in the EGR system. Here, the EGR valve is used to connect the exhaust manifold and the intake manifold. This valve is generally closed, so there is no EGR flow whenever the engine is cold, inactive, or t...

Turn the vehicle off and remove the key from the ignition. Allow the EGR valveample timeto cool down. Step 2 Open the hood and locate the EGR valve. The valve is mounted on the exhaust manifold. Refer to your vehicle repair manual for exact location and a diagram. Step 3 Turn the mul...
Hello I have disabled my EGR system by removing the magnet in the Egr Valve that operates the worm wheel mechanism . I did this as my car was shaking...
Pinging (spark knock or detonation) because the EGR system is not working, the exhaust port is plugged up with carbon, or the EGR valve has been disabled.Rough idle or misfiring because the EGR valve is not closing and is leaking exhaust into the intake manifold. You may also find a P...
FIG. 4 shows a timing diagram for pedal position, EGR valve position, intake air dilution, and CBV position, which may correspond to the engine system of FIG. 1 and the routines of FIGS. 2 and 3. DETAILED DESCRIPTION The following description relates to controlling LP EGR during operation ...
3 is a set of schematic diagrams of one embodiment of the positions of an optional rotary valve; [0016] FIG. 4 is a set of diagrams showing the lift profiles of the various valves of the engine with an electronic flow control system; [0017] FIG. 5 is a diagram showing effective ...
Problem to be solved: to perform EGR by dehumidifying the EGR gas from the cold state in a relatively simple configuration. The EGR system flows through the EGR passage 22, the EGR valve 23 and the EGR cooler 24, and the first EGR cooling water passage (each of the passages 44, 46, ...
The second bypass valve 43 is configured to transfer all the exhaust gas to one side or to divide it at a certain ratio and transfer it separately. The diesel-gasoline dual fuel powered engine to which is adapted the fouling free clean EGR system for a diesel-gasoline dual fuel powered ...
